Pros
  • A 60% duty cycle at full 200 A lets you run long aluminum beads without stopping
  • Pedal, torch and regulator in the box, so it is ready once you add gas
  • Runs on 120 V at up to 150 A, more than most rivals manage on household power
  • Pulse and lift start add control on thin stainless
Cons
  • At 40 lb it is heavy to carry for a 200 A machine
  • The stock 17 series torch is small for long high amp welds
  • A 3 year warranty is shorter than Everlast and ArcCaptain
